FULL PRODUCT VERSION :
java version "1.4.1_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_01-b01)
Java HotSpot(TM) Client VM (build 1.4.1_01-b01, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
Created an Instance of JTree.Added few nodes to the tree.Some of the nodes have same tooltip text.When mouseover a node tooltip is shown.
When the mouse is moved down to the node below with same tooltip the tooltip looks like its stuck there .In the program below when mouse is over the first node the tooltip is shown over the second node when mouse is over second node the tooltip still stays at the same place and it stays at same place even when mouse is moved to the 3rd node
Note: Mouse should be moved before dismissal delay.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the Program below
mouse over the first node of the tree
Then move the mouse over the second node
then move the mouse over the third node

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Expected to see the tooltip over
below the second node when mouse is on the second node and
below the third node when mouse is over third node
ACTUAL -
  Tooltip is always below the first node

REPRODUCIBILITY :
This bug can be reproduced always.
